​
Themes of the 2025 meeting will include:
​
-
Measuring the physical, mineralogical and chemical properties of systems across scale: new technologies
-
Architecture & geodynamics of systems at various scales
-
Mineralogy & chemistry of systems at different scales
-
Progress in system understanding & application to exploration
Topics for discussion include:
-
Use of SEM/LIBS scanning technolgies to support multi-element (MEs) and spectral mapping of mineral zoning of systems at deposit to district scales
-
Developments in MT imaging of roots and pathways of systems at crustal-scales
-
Redox gradients across the scales
One of the most challenging issues is mapping chemical gradients (the physico-chemical controls of metal transport & deposition such as temperature, redox, pH, H2O activity) at a range of scales. The meeting will examine mapping redox gradients (directly or with proxies) from the micro-scale to at least the terrain-scale.
..........and with luck there will be a speaker to tell us about the chemistry of the deep-Earth, or at least elements thereof, and potential source(s) of redox gradients in the deep-Earth.
​
The meeting will be preceded by a workshop on Archean Au systems, WA that covers:
-
Litho-geochemical approaches to defining architectural setting of systems.
-
New approaches to mapping alteration at deposit/district scales with SEM (TIMA) & LIBS datasets.
-
Use of isotopic & chemical gradients (redox, CO2 & H2O activity) as vectors.
-
Interaction of crustal and mantle fluids in systems and far field signals of productive systems
Timetable
